Robinson has been an integral piece of Seattle’s rushing attack since he arrived in 2010, having already played four seasons for the San Francisco 49ers. In 2011, he earned a trip to the Pro Bowl despite carrying the ball just four times, instrumental in finding holes and blocking tacklers for running back Marshawn Lynch.

He is well known for his veteran leadership and for his animated pre-game speeches to pump up his teammates. Robinson also produces the much-watched “Real Rob Report” video series on YouTube, in which he casually interviews his teammates and gives fans a peek inside the Seahawks locker room.

We will know for sure by 3 p.m. Saturday whether Robinson is cut. NFL teams must pare their rosters from 75 down to 53 men by then. If he indeed has been cut, that means the Seahawks have likely decided to hold on to fullbacks Derrick Coleman and rookie Spencer Ware.

Robinson was set to earn $2.5 million this year, higher than any other NFL fullback. Friday’s apparent cut could mean that the Seahawks might try to sign him back at a lower salary. Then again, as his tweet really suggests, he might be gone for good.
